Answer:

55 degrees.

Step-by-step explanation:

If you see that it is parallel. You can see that each angle on the top and bottom of it equals 360 degrees. So if the same 360 degree angle is at the bottom of these both. And both of then have 2 180 equalling degrees on the top and bottom of it. Then that would mean for the 125 the other side would have 55 degrees equalling 180. Same for the bottom so that would mean that it would be the same for the bottom 360 degree angle making me absolutely sure that X is equal to 55 degrees.

Answer:

Step-by-step explanation:

This is 55 because you need to make a sum of 180 when making a line and 125+55=180

Given that (x+y+z)(xy+xz+yz)=18 and that x^2(y+z)+y^2(x+z)+z^2(x+y)=6 for real numbers x, y, and z, what is the value of xyz?

Answer:

Step-by-step explanation:

$(x+y+z)(xy+xz+yz)=18$ Equation 1

$x^2(y+z)+y^2(x+z)+z^2(x+y)=6$ Equation 2

What is the value of $xyz$ where each variable represents a real number?

Let's expand equation 1:

$(x+y+z)(xy+xz+yz)=18$

$x(xy)+x(xz)+x(yz)+y(xy)+y(xz)+y(yz)+z(xy)+z(xz)+z(yz)=18$

Simplify each term if can:

$x^2y+x^2z+xyz+y^2x+xyz+y^2z+xyz+z^2x+z^2y=18$

See if we can factor a little to get some of the left hand side of equation 2:

The first two terms have $x^2$ and if I factored $x^2$ from first two terms I would have $x^2(y+z)$ which is the first term of left hand side of equation 2.

So let's see what happens if we gather the terms together that have the same variable squared together.

$x^2y+x^2z+y^2x+y^2z+z^2y+z^2x+xyz+xyz+xyz=18$

Factor the variable squared terms out of each binomial pairing:

$x^2(y+z)+y^2(x+z)+z^2(y+x)+xyz+xyz+xyz=18$

Replace the sum of those first three terms with what it equals which is 6 from the equation 2:

$6+xyz+xyz+xyz=18$

Combine like terms:

$6+3xyz=18$

Subtract 6 on both sides:

$3xyz=12$

Divide both sides by 3:

$xyz=4$

Can you help me with number 45 please ?

Katyanochek1 [597]

Answer:

h = 84

f = 132

g= 28

Step-by-step explanation:

h = 180 - 48 - 48 = 84

f = 180 - 48 = 132

g = 180 -132 - 20 = 28

Use the zero product property to find the solutions to the equation (x 2) (x 3) = 12.

The solution of the given equation is -6 and 1.

<h3>What is Quadratic Equation?</h3>

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

Here, given equation:

(x+2)(x+3) = 12

x(x+3)+2(x+3) = 12

x² + 3x + 2x + 6 = 12

x² + 5x + 6 - 12 = 0

x² + 5x - 6 = 0

x² + 6x - x - 6 = 0

x(x+6) -1(x+6) = 0

(x+6)(x-1) = 0

Now, x + 6 = 0 or x - 1 = 0

x = -6 or x = 1

Thus, the solution of the given equation is -6 and 1.

Answer: Yes, because the amount of money you save for every beverage bought is constant, and if you buy 0 beverages, you’ll save $0. That means it the situation is graphed, the line produced will be linear and crosses through the origin, which are the requirements for a proportional relationship.
